An electro-optical shutter for photography

The advent of the “all-electric” shutter makes possible the detailed photographic study of light from very rapidly changing self-luminous objects. Shutter control is sufficiently positive and accurate to permit operation at any pre-selected instant with a precision of 5 × 10

second. This article presents the theory and describes the development of this simple, reliable, and compact optical shutter which utilizes a Kerr cell as a light valve.
